Currently there's some CMO (Cooperative Memory Overcommit) code, in plpar_wrappers.h. Some of it is #ifdef CONFIG_PSERIES and some of it isn't. The end result being if a file includes plpar_wrappers.h it won't build with CONFIG_PSERIES=n. Fix it by moving the CMO code into platforms/pseries. The two hcall wrappers can just be moved into their only caller, cmm.c, and the accessors can go in pseries.h. Note we need the accessors because cmm.c can be built as a module, so there needs to be a split between the built-in code vs the module, and that's achieved by using those accessors.
